Title: Increasing Oil Production through EOR at the Offshore Captain Field
Abstract: Summary The Captain field located in the UK continental shelf of the North Sea contains shallow sandstone reservoirs of high quality and permeability and was developed with produced water re-injection to maintain the reservoir pressure. However, the Captain reservoirs contain a relatively heavy oil with moderately high viscosity, which has an unfavourable mobility ratio to water and resulted in early water breakthrough, with oil production at high watercuts and a long production duration at low oil rates. In this paper we present recent results from the successful polymerflood Enhanced Oil Recovery (EOR) development, which have accelerated and increased oil recovery from the field. Polymerflood EOR began in 2011 at Captain with a single successful pilot and additional polymerflood developments have been implemented across larger areas of the reservoirs. These successive developments have continued the success of polymerflood EOR implementation and demonstrate the applicability of this technology across the Captain field. Recent results from EOR at Captain are presented, which demonstrate the ability of a polymerflood development to consistently reduce watercuts, increase oil production and maximise overall oil recovery in an offshore location, thereby significantly improving the efficiency of oil production from the field.
